Note, this is the diff of the bad edit. It's a little confusing because some of these fields I did change:

http://wikiapiary.com/w/index.php?title=Ultipedia&diff=273776&oldid=260530

Note that Audited, Active values should *not* have changed.

Also, the form edit screen didn't have the Image in it.

I used "undo" on that change, then reverted to the previous commit and did the same edit and worked as expected.

I changed the title from "Semantic Forms master loses current form/template values" to "[SF] Some Boolean values change from "Yes" to "No"".

What's "the Image" that you're talking about?

The field

{{{field|Image|uploadable|image preview|default=Default website image.png}}}

on this form

http://wikiapiary.com/wiki/Form:Website

also reverted back to default when edited with the current master.

I checked out master again, did Edit with Form and then did a Show Changes to see what it was not keeping (without editing anything). It lost values in text fields and checkboxes. It seems like the ones that lost value are mostly (maybe all) ones that have defaults specified.

That makes sense - I retitled it again.

Yep, sorry for the confusion.

I think this is fixed now; thanks for the bug report.

I pulled 8add8efadb8976c5dafb34870a9dc5039e13cbc5 and verified that the defaults are not being applied on an existing value.
